First, the small diameter stainless steel pipe is a continuous production of thin-walled stainless steel line pipe, wall thickness thicker units and welding equipment investment, the greater the stainless steel pipe company, the more it does not have the economic and practical. Thinner wall thickness, it will be a corresponding decline in the input-output ratio; secondly the product of the process to determine its strengths and weaknesses, high precision welded steel pipe is generally uniform thickness, the tube looks bright and high (steel pipe surface level of the decision surface brightness), can be any length. Therefore, it reflects its economy and aesthetics in high-precision, low-pressure fluid applications. Welding techniques can be divided according to automatic welding, manual welding. Automatic submerged arc welding generally use, plasma welding, manual TIG welding generally use. . To ensure that the conditions under the current provisions of the standard project to test and ensure compliance with the standards, called guarantee conditions. Ensure that terms and conditions are divided: A, the basic guarantee of condition (also known as a necessary condition). Regardless of whether the customer specified in the contract. Required by the provisions of the standard test Shandong stainless steel pipe, and to ensure that the test results meet the standard requirements. Such as chemical composition, mechanical properties, size deviation, surface quality and testing, hydrostatic test or crushed or flaring process performance and other experiments, are a necessary condition. B, the agreement to ensure that the conditions: standard, in addition to the basic guarantee conditions, there are "based on the demand side, the supply and demand sides negotiated, and note in the contract quot; or?" When the demand side ...... stainless steel pipe, should be specified in the contract "; there are customers, to ensure that the conditions put forward the basic standards tightened requirements (such as composition, mechanical properties, size deviation, etc.) or by inspection items (such as steel pipe ovality, uneven wall thickness, etc.) these provisions. and requirements, when ordering, negotiated by both parties signed the agreement and supply technology specified in the contract. Therefore, these conditions are also known as protocol ensures that conditions there is an agreement to ensure that the conditions of the product, like all want to increase the stainless steel round 304_ tube professional manufacturers (certified) _ stainless steel pipe provided by Shandong Jinding Stainless Steel Pipe Industry Co., Ltd. Shandong Jinding Stainless Steel Pipe Co., Ltd. (www.jdbxg.cn) is Dezhou, steel leader, over the years, the company is implementing implementation of scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In Jinding tube industry leadership with the staff warmly welcome all inquiries negotiations to create Jinding pipe industry a better future.
